Positive and negative urgency reflect specific facets of impulsivity and correlate with several health-related risk behaviors such as aggression, substance use, and suicide. Less is known about how positive and negative urgency are associated with suicidal behaviors of diverse racial groups.
To investigate racial differences in the positive associations between positive and negative urgency and suicide in children in US.
This longitudinal study used the Adolescent Brain Cognitive Development (ABCD) study. Participants were 10535 American children between ages 9 and 10 years old who were followed for up to one year. The independent variable was suicide history. The primary outcomes were the positive and negative urgency measured by the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale (UPPS-SS). Mixed-effects regression models were used for data analysis.
In the overall sample, suicidality was associated with positive and negative urgency in children. Race showed a statistically significant interaction with suicidality on children's positive and negative urgency, indicating stronger effects of suicidality on positive and negative urgency for White, compared to Black and Other/Mixed race children respectively.
The effects of positive and negative urgency for suicidality of American children depend on race. White American children show the strongest links between positive and negative urgency and risk of suicide, while the effects of positive and negative urgency on children suicide are weaker for Black and Other/Mixed race children.
积极冲动和消极冲动反映了冲动性的特定方面，并与多种与健康相关的风险行为相关，如攻击行为、物质使用和自杀。关于积极冲动和消极冲动如何与不同种族群体的自杀行为相关，我们所知较少。
研究美国儿童中积极冲动和消极冲动与自杀之间正向关联的种族差异。
这项纵向研究采用了青少年大脑认知发展（ABCD）研究。参与者为10535名9至10岁的美国儿童，随访时间长达一年。自变量是自杀史。主要结局是通过冲动性、预谋性（缺乏）、坚持性（缺乏）、冒险寻求、积极冲动、冲动行为量表（UPPS-SS）测量的积极冲动和消极冲动。采用混合效应回归模型进行数据分析。
在总体样本中，自杀倾向与儿童的积极冲动和消极冲动相关。种族在儿童的积极冲动和消极冲动方面与自杀倾向存在统计学上的显著交互作用，表明与黑人和其他/混合种族儿童相比，自杀倾向对白人儿童的积极冲动和消极冲动影响更强。
美国儿童中积极冲动和消极冲动对自杀倾向的影响取决于种族。美国白人儿童在积极冲动和消极冲动与自杀风险之间的联系最为紧密，而积极冲动和消极冲动对黑人及其他/混合种族儿童自杀的影响较弱。
